Can You Change Builders After Your Construction Loan Closes?
Editorial review: My Construction Path team ·
Yes, in most cases, but not on your own. The lender has to agree, approve the new builder and accept a new contract and budget before it releases more draws. It will also check that the first builder's subs and suppliers were paid, so no liens follow you. Extra cost usually comes from contingency funds or your own cash.

Why does your lender have to approve a builder change?
Your loan was approved for a specific builder, contract and budget. Switching changes all three, so the lender has to sign off first.
On a one-time close, the lender controls the build money. Fannie Mae's Selling Guide says the lender "will be responsible for managing the disbursement of the loan proceeds to the builder, contractor, or other authorized suppliers." Your loan documents likely describe what happens if the builder stops work or the contract ends. Read them, then call your loan officer before you act.
What are the steps to switch builders mid-build?
Most changes follow the same order. Skipping a step usually stalls draws, and a switch adds time to builds that already run long. As of the Census Bureau's 2025 annual data, published July 1, 2026, contractor-built homes took an average of 10.5 months from start to completion (Census start-to-completion table).
| Step | What happens | Why it matters |
|---|---|---|
| 1. Talk to your lender | Explain the problem and ask what it needs | Draws may pause until the change is approved |
| 2. Document the problem | Write down unfinished or faulty work, with photos and dates | Protects you if the old builder disputes the end of the contract |
| 3. End the old contract properly | Follow its termination terms, ideally with an attorney | A bad exit can lead to claims or liens |
| 4. Get the work inspected | The lender's inspector confirms what is done | Sets the starting point and budget for the new builder |
| 5. Approve the new builder | The new builder sends the lender's packet | Same review as any builder approval |
| 6. Sign a new contract and budget | Covers only the remaining work | The lender checks the loan still covers the finish |
| 7. Restart draws | Inspections and draw requests resume | Money flows only for work that is complete |
What happens to the old builder's contract?
It has to end, or be formally assigned, before a new builder takes over. An assignment hands the existing contract to the new builder. A new contract is more common.
Start with a written notice. Maine's Attorney General suggests writing to a contractor who left work unfinished or done wrong. The letter should describe the work and ask when it will be finished. If the contractor won't finish, you may be able to hire someone else and seek your losses (Maine Attorney General). Rules differ by state, so get legal advice where you're building.
If the old builder holds a deposit, see how a builder deposit affects your construction loan.
How do lien waivers and draws work during a switch?
The lender wants proof that everyone paid through the old builder was actually paid. Unpaid subs and suppliers may be able to file liens against your home.
Maine's Attorney General warns that "A contractor or subcontractor who works on your home, or the land around it, can obtain a mechanic's lien against your home if they are not paid." It also explains, "A lien waiver is evidence that the person who gave the waiver received payment in the amount indicated" (Maine Attorney General).
Expect the lender or title company to ask for waivers from the old builder and its major subs, plus an updated title check. Then draws restart under the new contract. For how draws normally work, see how construction loan draws work.
Who pays if the new builder costs more?
You do, unless contingency funds cover it. A new builder taking over a half-finished job often prices in risk, fixes and its own margin.
The usual sources are:
- Contingency reserve. This is what it is for. Our contingency calculator shows how much cushion a budget may need.
- Your own cash, deposited with the lender before draws resume.
- A loan increase, if the lender allows it and the appraisal supports it.
- Scope changes, such as simpler finishes, to bring the budget back in line.
For more on gaps between budget and cost, see what happens if your builder goes over budget. If the switch also delays the finish, read what to do if your build is over budget or behind schedule.
How do you lower the odds of needing a new builder?
Choose and document carefully at the start. A few habits help:
- Check licenses, insurance and recent references before you sign.
- Use a contract with clear schedule, quality and termination terms.
- Put every change in writing. In Maine, the Attorney General notes that "Any change in the work or materials that changes the contract price must be stated in a written change order that is signed by both parties" (Maine Attorney General).
- Watch draw inspections, and ask questions when progress and payments don't line up.

Frequently asked questions
Can I change builders after getting a construction loan?
Usually, but only with your lender's written consent. The new builder must pass the lender's review, and the lender will want a new contract, an updated budget and a clean lien position before draws restart.
Will my lender pay the new builder?
Once the lender approves the new builder and contract, it releases remaining draws to that builder after inspections, the same way it paid the first one.
What if the new builder costs more?
The gap has to be covered by contingency funds, your own cash or, in some cases, a loan increase the lender approves. Get the new bid before you end the old contract.
Do I need a lawyer to end my builder contract?
It is wise. Ending a contract the wrong way can create claims or liens. A real estate or construction attorney can review the termination terms.
